An equation can be any of the following: • 2 + 2 = 4 is a equation because .
• 2 + 3 = 4 is a equation because .
• 2 + x = 4 is a equation because .

Step-by-step explanation:

2 + 2 = 4 is a equation becuase the sum of LHS = RHS

2 + 3 = 4 is a equation becuse the sum of LHS is not equal to RHS

2 + x = 4 because x is 2 and LHS is equal to RHS

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
